This database contains monthly returns from U.S. Regular Army regiments received by the Adjutant General’s Office from June 1821 to December 1916. It also contains other forms and correspondence that were filed with these returns.

The Regular Army monthly returns were to report on the strength of each regiment, including total numbers of men present, absent, sick, or on extra daily duty, as well as to give a report of officers and enlisted men by name. Later returns included an accounting of strength in terms of horses and artillery.
